WILLIAM H. WALKER, OF NORTH ENID, OKLAHOMA, ASSIGNOR OF ONE-HALF TO ERNEST GOLL, 0F KREMLIN, OKLAHOMA.

RAILWAY-CROSSING SIGNAL.

Application filed January 14, 1916. Serial No. 72,086.

To all whom it may concern:

Be it known that I, VVILLIAM H. WALKER, a citizen of the United States, residing at North Enid, in the county of Garfield and State of Oklahoma, have invented certain new and useful Improvements in Railway- Crossing Signals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in railway crossing signals and the principal object of the invention is to provide an audible signal operative upon the approach of a train toward a railroad crossing to warn persons approaching the tracks of the danger.

Another object of the invention is to'provide a device which will operate without the use of electricity or other similar power.

Still another object of the invention is to provide a mechanically operated device, which is controlled by the passage of wheels over a suitable trip mechanism.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which Figure 1 is a perspective view showing this improved device in position for use, and

Fig. 2 is a sectional View showing the details of construction.

Referring now to the drawings by characters of reference, the numeral 1 designates the ties of the railroad track, while the numeral 2 designates the rails. One of the ties 1 which is designated by the numeral 3 is provided with a cut-away portion forming the tongue 4, which provides a base plate on which the operating mechanism is mounted.

Extending upwardly from the base plate is a suitable standard 5. the web of one of the rails 2 is a plate 6, which plate and standard 5 are formed with openings 7 in which the trunnions of the operating shaft are journaled.

The operating shaft hereinbefore referred to is designated generally by the numeral 8 and comprises a. single strip of metal provided with suitable ears 9. Extending from the ears are trunnions 10, as clearly shown in the drawings. Extending upwardly from Specification of Letters Patent.

Secured against Patented Ja 21, 1919.

the shaft 8 at one end portion thereof and adjacent one of the ears 9 is a trip plate 11 having formed at its upper edge, a bead 1.2.

Riveted or otherwise secured at the opposite end of the shaft is a suitable lever 13, the lower end of which is provided with an opening 14: through which the actuating cable 15 extends. This actuating cable extends through an opening 14 and is secured to the lever in any suitable manner. The opposite end of said cable is connected to a suitable operating lever 16 of the bell 17. It is to be understood that if so desired suitable pulleys 18 may be secured to the ties intermediate the operating lever and the bell in order to support the flexible member 15 and hold the same against frictional engagement with the ties, thereby preventing wear thereon.

In order to hold the plate 11 in position to be operated, there is connected on one side of the plate a suitable spring 19 and secured on the opposite side of the plate is a spring 20, which pulls against the spring 19 to hold the plate in a vertical position. The opposite ends of the springs 19 and 20 are connected to suitable eyes mounted in ties which are spaced from the shaft 8 so that the pull of one spring will be equalized by the pull of the other.

t will be apparent from the foregoing that in use as the wheels of the train pass over the rails and by the signal the overhanging portions of said wheels will engage the plate 11. thereby rocking the same an exerting pull on the flexible member 15 which will cause the lever 16 to oscillate and ring the bell.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the appended claim.

What is claimed is A railway crossing signal adapted for attachment to the tie and a rail of a railway line, said signal comprising, a vertical standard secured to one of the tie and spaced from the rail; a bearing plate attached to the outer side of the rail; a shaft rotatably carried by said vertical standard and said plate; a wheel contact plate projecting slightly above the ball of the rail and formed integral with said shaft; coil springs'conby the engagement of a moving car Wheel nected to opposite sides of said contact plate of said plate. 10 and adapted to' no'rmally retain the same lntestimony whereof Taflikmysignatfiie in a vertical position, said coil springs havin presence oftwo Witnesses.
